GUARD FOR GRAIN-BINDER CONVEYERS.

. Application filed. May 1,

To ZZ whom, 'it may conce/m.

Be it known that I, JOHN' C. Bini'r'rnv, a citizen of the United States,residing at St. Paul, inthe county oi Ramsey and State ot Minnesota,have invented certain new and usc'l'ul Improvements in Guards for Grain-Binder Conveyers, oi' which thefollowing is a specification. v Y

My invention relates to attachments for grain binders, and the object isto provide a guard over the front edge of the endless apron or conveyerthat conveys the cut grain to the elevator ot a binder. Said guardprevents wear and tear of the front edge of the conveyer and alsoprevents said edge and the ends of the cleats thereon from catching andtangling` the grain especially when the grain is ifniXed with vines andweeds of various kinds as is often the case, and to save short graintrom escaping from the machine.

In the accompanying drawing:

Fig. 1 is a perspective iront view of the main portion ot a binder withmy'attachnient applied to it. f

Fig. 2 is an enlarged section on theI line 2-*2 in Fig. l.

Fig. 3 is a detail front .view of my attachment removed from the binder.

Fig. a is the same as Fig. 3 only that it is designed to go on a binderhaving a right hand conveyer while that in Fig. 3 is for a binder havinga lett hand conveyer that is a conveyer on the left side of the driver.

Referring to the drawing by reference numerals, 5 designates the reel, 6the elevator, 7--71 the endless apron or conveyor moving the cut grainto the elevator. 8 and 8a are the usual grain dividing or guidingdevices at the front end of the machine, while 9 indicates the sicklebar having sickles 10 coacting with guards 11 to cut the grain. All ofsaid parts are mounted in suitable 'framework only partlyshownfsupported on the usual ground wheels like l2 and the bull wheel13, from which latter operative motion is transmitted to all theworking` parts ot the machine. The strncture so far described is variedin some maires of binders but so general in all binders that I need notdescribe the saine any further in detail. y

I may state, however, as to Fig. 2 that the horizontal traine oi theendless conveyeif' is or may be considerably varied incon-l struction;thus its front sill le may'. be

secured to the rear sill or connected with it by any suitable number andshape of cross bars'l, and longitudinal bolt rods (not shown), or inlieu et such rods it is common to use barsl l7 in Figz having flattenedangularly bent ends 1S secured to thegsills -i and l5 by bolts i9 and 20respectively.

Each bolt 20, whether short or long, is

always longenougli outside the frame to receive a washerQl and anut-21a.

My attachment consists ot an angle bar preferably made ot galvanizedsheet iron and formed with ya vertical iange 23 khaving a series ofdownwardly open notches 2 adapted to be slipped downwardly upon severalof the bolts 2O and be held tightly, thouoh removably, on the sill la bythe washers 2l and nuts 21a. The angle bar also has a horizontal LlangeQL projectingrear* wardly upon the front edge of the conieyer 7 and thefront ends of the cleats 7u thereof (see Fig. 2). Said horizontal flangehas at one endan extension 25 projecting,` upwardly and horizontallyupon the lower portion ot' the lower member 6a of the inclined elevator@-63 so as to prevent grain from dropping downwardly over the adjacentend ot the endless conveyer 7.

In Fig. 3 24a is a slotted hole to indicate that such holes may take theplace of the notches 24. In Fig. 2 26 indicates a solid plate or board stiifening the traine M-fl 16.

lhile I `have shown my invention as an attachment readily securablc uponthe asually existing bolts at the `trent ot a binder conveyer, it willbe uncerstood that for binders not already having such bolts it is easyto furnish either bolts, lag-screws or cap screws for the purpose, andit' my device is put on the binder at the -factory it may be secured inplace by rivets or any other suitable means.

As already stated, the devicefprevents tangling and clogging, and savesthe front part of the conveyer from undue wear and it also aids insaving short grain by preventing its escape at the foot ot the elevator.

l/Vliat I claim is: n

l. The combination with a grain binder liavingg, the usual platformtraine and an endless conveyer and an inclined elevator arranged toreceiveV the cutvgrain'troin the conveyer; said trame having a frontsill, guard lingers projecting ironiythe lower edge of thesill, ananglebar lhaving a vertical flange secured by bolts to the 'front side olfthe upper portion of the sill and a horizontal flange projecting looselyover the' lront edge ot the conveyor apron.
